Can detect the biosensing apparatus of test piece code and corpse or other object for laboratory examination and chemical testing lack of fill

Technical field

The present invention relates to a kind of biological sensing test sheet and its display processing unit, a kind ofly have Auto-Sensing test piece code but particularly relate to, and can detect corpse or other object for laboratory examination and chemical testing loading whether enough test piece detected code and the biosensing apparatus of corpse or other object for laboratory examination and chemical testing lack of fill.

Background technology

due to developing rapidly of sensor technology in recent years, the various biological sensors of ferment redox reaction that utilize constantly are suggested, and one after the other weed out the old and bring forth the new, wherein, again with the most species of the biological sensor of biomedical sector, for example: the blood sugar sensor, it can be in order to check the blood-sugar content in blood, therefore, the blood sugar sensor becomes the important device of diabetic's self-checking, it can help the diabetic oneself to detect the concentration of blood-sugar content in health, make the diabetic can momentarily note and control blood sugar concentration in health, within blood sugar concentration is maintained normal scope, in case the blood sugar concentration of Finding case health is too high, just can be by diet, the modes such as motion and insulin injection, control blood-sugar content, yet, these control modes must just permit with employing under doctor's supervision and suggestion.

See also Fig. 1 and Fig. 2, a kind of stereographic map of the existing blood sugar sensing apparatus of commonly using and a kind of exploded view of the existing blood sugar sensing test piece of commonly using, a kind of existing blood sugar sensing apparatus 1 ' of commonly using, comprise: a blood sugar sensing test piece 12 ' and a processes and displays unit 10 ', wherein, this blood sugar sensing test piece 12 ' comprising: a strip substrate 122 ', a responding layer 124 ', a spacing body 126 ', an and cover plate 128 '.The front end of this strip substrate 122 ' is provided with an electrode part 1221 ', the top of this electrode part 1221 ' sequentially is coated with this responding layer 124 ', this spacing body 126 ' and this cover plate 128 ', and, be provided with operation electrode a 1222 ' electrode 1224 ' corresponding on electrode part 1221 ', this operation electrode 1222 ' and this counter electrode 1224 ' are connected to respectively one first wire 1226 ' and one second wire 1228 ' of strip substrate 122 ' tail end.In addition, be covered in the responding layer 124 ' of electrode part 1221 ' top, it has ferment enzyme can carry out the ferment redox reaction.

the diabetic states in this existing blood sugar sensing apparatus 1 ' of commonly using in the use, first this blood sugar sensing test piece 12 ' is inserted among this processes and displays unit 10 ', then, the patient must be first with a test piece code (strip code) the input processing display unit 10 ' of blood sugar sensing test piece 12 ', then just can take the blood of own body, and blood is directly dripped on this responding layer 124 ' of blood sugar sensing test piece 12 ', after electrochemical reaction after a while, processes and displays unit 10 ' just can be by the curent change that reads electrochemical reaction and produce, and calculate blood sugar concentration among blood.
